It looks like 2025.3.1.1 has been removed.

The flutter plugin uses 2025.2.3.9 and I'm inclined to move to that.

Observations:

1. we should probably use the same ideaVersion for both plugins
2. we should have a better system for tracking and pinning the stable build version
3. (this would be moot if we had a single build for both or a combined plugin

The flutter plugin uses 2025.2.3.9 and I'm inclined to move to that.

Alternatively, we could bump to 2025.3.4 which is freshly out.

But, hrmmmm, I'm confused about the maven repo structure.

Looking at https://repo.maven.apache.org/maven2/, I'm not seeing an idea subdir?

Trying this.

Re-opening as we're failing still/again.

As of 4/25, we're green again. It's possible some of our recent deps updates fixed something or that the breakage was a symptom of a temporary kokoro issue. 🤷

Optimistically closing as fixed.

Re-opening to track newly introduced failures.

The good news is we now have builds on presubmits (#362) and a PR that rolls us back before the breakage (#363). The next step is to figure out how we want to thoughtfully roll back and forward to identify the actual breaker. (My money is on one of the dependabot changes.)
